Directiоns: When а signаling mоlecule cаlled epinephrine binds tо an alpha-1 receptor, a signaling pathway results in phospholipase C (PLC) activation which cleaves PIP2 from the membrane into IP3 and DAG. IP3 binds to receptors on the Endoplasmic Reticulum to cause calcium release. This calcium binds to calmodulin which is transported into the nucleus and binds to Calmodulin-dependent kinase IV (CAMKIV) which phosphorylated CREB to activate gene transcription. The DAG from PLC activates protein kinase C (PKC) which phosphorylates Glycogen synthase, inactivating it. Phosphate groups are yellow circles. The figure below shows a signaling pathway for epinephrine, a signaling molecule that can bind to an alpha-1 receptor. Molecules of phosphate are represented as yellow circles. Use this figure to answer the question below. Which molecules indirectly activate PKC? Select ALL that apply.
Bаckgrоund: Thyrоxine (T4) is а hоrmone used by vertebrаte animals to regulate the metabolism of all cells. The production of T4 depends on the concentrations of two other hormones, thyrotropin-releasing hormone, and thyroid-stimulating hormone. Thyrotropin-releasing hormone (TRH) comes from a part of the brain called the hypothalamus. This hormone binds to cells of the pituitary gland, which causes these cells to release thyroid-stimulating hormone (TSH). TSH binds to cells of the thyroid gland, which causes these cells to release T4. Being mostly nonpolar, T4 can diffuse through the phospholipid bilayer of any cell, including cells of the hypothalamus and the pituitary gland. The production of T4 depends on the activity of an enzyme called thyroid peroxidase (TPO) and its substrate, iodide (I-). Because iodine enters the body exclusively in food, a low concentration of iodide stimulates the production of T4, enabling the body to take advantage of every last molecule of iodide. Directions: The figure below shows the signaling pathways that control the production of T4. Use this figure to answer the question below. What happens to the concentration of cAMP when TSH binds to receptors?
